An object with reflection-reducing coating includes a substrate and a coating arranged on the substrate. The coating is multilayered and includes an outer layer having a refractive index n1 and at least one second sub-layer with a refractive index n 2 which is adjacent to the outer layer. n 2 >n 1 +0.4, and the outer layer possesses a refractive index n 1 >1.50 and a layer hardness greater than 8 GPa. |
